opencode vs zero
Terminal-based AI coding agents compared
opencode and zero are open source coding agents that help developers work with repositories from a terminal. opencode distinguishes build and read-only plan agents and also offers a beta desktop app, while zero emphasizes configurable permissions, model choice, persistent sessions, and scriptable execution.
opencode: Work with an Open Source AI Coding Agent
OpenCode is an open source AI coding agent for developers who want AI assistance in their coding workflow. It offers build and read-only plan agents, a terminal UI, and desktop apps in beta.
zero: Run a Local Terminal Coding Agent
Zero is a Go-based terminal coding agent that can inspect and edit repositories, run commands, and work with many hosted or local models. It suits developers who want scriptable coding assistance with local sessions and explicit controls over side effects.

Key differences
- opencode is written in TypeScript, while zero is written in Go.
- opencode provides a full-access build agent and a read-only plan agent; zero uses configurable permissions and sandbox policies for actions such as file writes and shell commands.
- zero offers a headless `zero exec` command with structured I/O for scripts and CI; opencode centers on its terminal UI and agents.
- zero supports hosted providers, local model services, and compatible endpoints; opencode's supplied details focus on its agents and ways to install the application.
- opencode offers a beta desktop app for macOS, Windows, and Linux; zero's described interfaces are an interactive TUI and a headless command.
Choose opencode if you…
- want distinct build and read-only plan agents for coding and code exploration.
- prefer a terminal agent with a beta desktop app available as an alternative.
- want installation options such as npm, Homebrew, Scoop, or an install script.
Choose zero if you…
- need a headless command with structured input and output for scripts or CI.
- want to choose between hosted models, local model services, and compatible endpoints.
- need local sessions that can be searched, resumed, forked, or rewound, with configurable action permissions.
